A Proud Sister - Murata Himeko x dying sister! reader

Hi guys~! So here is a various anime/games x reader well, it's already as the title states but I'm warning you, this is going to be angsty (as much as possible) (-and nasty-)...

Ps. Some content might trigger you so if you are not up to this kind of story, then think twice before reading but anyways... Enjoy~!

(WARNING: A very slow and unproductive author here 0-0...)
